Question

How do i use coordinate geometry to find the midpoint AB?

Answer 1

To find the mid point of the line segment Ab you have to get the coordinate sof point A and B respectively.

Mid point formular can be represented as follows

`\begin{gathered} \text{mid point = (}(x_1+x_2)/(2),(y_1+y_2)/(2)\text{)\_} \\ \end{gathered}`

A(-2,-2 ) and B(3,7)

`\begin{gathered} \text{mid point}=((-2+3)/(2),(-2+7)/(2)) \\ \text{mid point=(}(1)/(2),(9)/(2)\text{)} \end{gathered}`
